fastback shapes

3. When a discredited idea is trumpeted again and again by the same person, I'd call that idea rubbish.
* The streamlined body represented by the 'template' is a fastback.
* A streamline body, taken to its conclusion, possesses zero flow separation.
* A streamline body recovers all static pressure, less what's lost to surface friction drag.
* The static pressure acting on a streamline body is nearly identical at nose and tail. It's incapable of generating lift.
* You've never analyzed a streamline body.
* None of your measurements are germane to streamline bodies.
* Hucho is a champion of streamline bodies, the only path to really low drag. Germany thought enough of his work that it's in their national museum.
